Is it possible to add Swing into a composition?

I just got Musescore a few weeks ago and i'm still in the process of figuring things out, but is it possible to add swing to the tempo some how? I looked it up briefly on this website and I found something saying to drag a picture file into the score of a swing tempo, but that didn't work for me.

Well, not while it is being played, no. Bring up the play panel while the piecw is stopped, make the change from straight to swing, then start playback. It will stay swing forthe duration of the session.
